Dark Energy Survey Year 6 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Adamow +169
We present cosmology results combining galaxy clustering and weak gravitational lensing measured in the full six years (Y6) of observations by the Dark Energy Survey (DES) covering…
What Galaxy Clusters Have to Say About Dynamical Dark Energy and
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +4
We show that, in flat CDM, low-redshift structure probes -- cluster abundances, 32-point analyses, and full-shape clustering -- are mutually consistent, jointly deliveri…
Cosmological Constraints from Dark Energy Survey Year 1 Cluster Lensing and Abundances with Simulation-based Forward-Modeling
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +7
We present a simulation-based forward-modeling framework for cosmological inference from optical galaxy-cluster samples, and apply it to the abundance and weak-lensing signals of D…
Association between optically identified galaxy clusters and the underlying dark matter halos
DES Collaboration, Shulei Cao, Hao-Yi Wu +10
Clusters of galaxies trace massive dark matter halos in the Universe, but they can include multiple halos projected along lines of sight. As a case study, we quantify the propertie…
Robustness of pairwise kinematic Sunyaev-Zel'dovich effect to optical-cluster-selection bias
Y. -H. Hsu, D. Gruen, P. A. Gallardo +5
The pairwise kinematic Sunyaev-Zel'dovich(kSZ) effect measures both the pairwise motion between galaxy groups and clusters and the amount of gas within them, providing a tracer for…
Dark Energy Survey Year 3 Results: Cosmological Constraints from Cluster Abundances, Weak Lensing, and Galaxy Clustering
DES Collaboration, T. M. C. Abbott, M. Aguena +88
Galaxy clusters provide a unique probe of the late-time cosmic structure and serve as a powerful independent test of the CDM model. This work presents the first set of cosmologi…
Dark Energy Survey: Modeling strategy for multiprobe cluster cosmology and validation for the Full Six-year Dataset
Chun-Hao To, Elisabeth Krause, Chihway Chang +63
We introduce an updated To&Krause2021 model for joint analyses of cluster abundances and large-scale two-point correlations of weak lensing and galaxy and cluster clustering (terme…
Optical galaxy cluster mock catalogs with realistic projection effects: Validations with the SDSS clusters
Andy Lee, Hao-Yi Wu, Andrés N. Salcedo +9
Galaxy clusters identified in optical imaging surveys suffer from projection effects: Physically unassociated galaxies along a cluster's line of sight can be counted as its members…
Forecasting the constraints on optical selection bias and projection effects of galaxy cluster lensing with multiwavelength data
Conghao Zhou, Hao-Yi Wu, Andrés N. Salcedo +12
Galaxy clusters identified with optical imaging tend to suffer from projection effects, which impact richness (the number of member galaxies in a cluster) and lensing coherently. P…
Dark Energy Survey Year 1 Clusters are Consistent with Planck
Andrés N. Salcedo, Hao-Yi Wu, Eduardo Rozo +4
The recent Dark Energy Survey Year 1 (DES-Y1) analysis of galaxy cluster abundances and weak lensing produced and constraints in 5.6 tension with Planck. It is…
Cosmological Constraints from Galaxy Clustering and the Mass-to-Number Ratio of Galaxy Clusters
Jeremy L. Tinker, Erin S. Sheldon, Risa H. Wechsler +8
We place constraints on the average density (Omega_m) and clustering amplitude (sigma_8) of matter using a combination of two measurements from the Sloan Digital Sky Survey: the ga…
The Effects of Halo Assembly Bias on Self-Calibration in Galaxy Cluster Surveys
Hao-Yi Wu, Eduardo Rozo, Risa H. Wechsler
Self-calibration techniques for analyzing galaxy cluster counts utilize the abundance and the clustering amplitude of dark matter halos. These properties simultaneously constrain c…
Measuring the mean and scatter of the X-ray luminosity -- optical richness relation for maxBCG galaxy clusters
E. S. Rykoff, T. A. McKay, M. R. Becker +6
Determining the scaling relations between galaxy cluster observables requires large samples of uniformly observed clusters. We measure the mean X-ray luminosity--optical richness (…
The Mean and Scatter of the Velocity Dispersion-Optical Richness Relation for maxBCG Galaxy Clusters
M. R. Becker, T. A. McKay, B. Koester +9
The distribution of galaxies in position and velocity around the centers of galaxy clusters encodes important information about cluster mass and structure. Using the maxBCG galaxy…
